I am aware that no one will answer to Bitcoin ownership, it is privacy and it becomes very vulnerable to being known by the public.
It is also because the price of Bitcoin is expensive and has always reached ATH to date.
In this case, you should understand how soon this topic will become a mega thread containing the same type of answers.

But yes, your selection of people who had many bitcoins makes me remember and maybe a little sad about missed opportunities. I also found quite a few posts where people simply did not know what to do with bitcoins and simply sold them for pennies. However, this is history and worth remembering.
